A Multicenter, Randomized Controlled Trial to Assess Video-Based Surgical Coaching in Gynecology
Bibliographic record
Abstract
STUDY OBJECTIVE: To evaluate the effect of video-based coaching on technical skill development in surgical education. DESIGN: Randomized controlled trial with video-based coaching (intervention group) in addition to standard surgical curriculum or the standard surgical curriculum alone (control group). SETTING: Laparoscopic vaginal vault closure in the operating room at 3 academic hospitals. PARTICIPANTS: Senior Obstetrics and Gynecology residents (year 3-5) on their chief resident or gynecologic oncology rotation. INTERVENTIONS: All residents were recorded performing laparoscopic closure of the vaginal cuff prior to randomization. Surgical coaching sessions followed the Wisconsin Surgical Coaching Framework over 30 minutes on Zoom with one surgical coach. All residents were recorded subsequently performing the same surgical technical skill. Blinded, expert surgeons performed the video assessment using the OSATS, GOALS, and global rating scale. The mean change in operative time and the mean change in video-assessment score between the 2 video-recorded attempts were compared between groups. Qualitative semi-structured interviews were conducted to understand the residents' perspective on video-based surgical coaching. MEASUREMENTS AND MAIN RESULTS: Twenty residents participated with 10 in the coaching and 10 in the control group. Mean operative time to complete the suturing task was reduced by 32.8% (SD = 21.3%) in the coached group vs 7.2% (SD = 25.1%) in the control group (p = .025). There was no significant change in surgical assessment scores within the coached or control group. Residents identified the core components of a surgical coaching program to include: (1) the resident: focused skill development, (2) the coach: focused on feedback, (3) and the coaching program: a structured activity. Residents envisioned monthly coaching with the opportunity for deliberate practice, the importance of a positive relationship between the coach and coachee, and the importance of faculty development in surgical coaching. CONCLUSION: Video-based surgical coaching is an effective tool to enhance technical skill development in surgical education.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
